Samsung U8000F (VA) vs TCL C7K / QM7K

While the U8000F with a VA panel can still be praised for decent blacks, there is no longer any reason to be enthusiastic about brightness – especially in HDR scenes. The television achieves a maximum of just under 250 nits, which is simply too low to speak of any impressive light effects. Bright elements appear pale, and scenes that should sparkle look rather flat. We observed an interesting situation during the test of a scene from the film Sicario 2 – the screen became noticeably darker, as if the television was trying to hide its limitations in displaying blacks. One might get the impression that the device artificially darkens the image to enhance contrast, but in practice, the effect makes very little difference, other than the fact that we see less on the screen. Furthermore, there is the issue of colours – the U8000F does not support a wide colour gamut, so one cannot count on the vibrant, saturated hues known from better models. The HDR image here resembles slightly brightened SDR and... perhaps that is even a good thing. With this model, it is not worth expecting a cinematic experience – it is better to treat HDR as a modest addition.

TCL C7K is one of the brightest MiniLED televisions in its price range. Under the best testing conditions, the screen managed to achieve over 1200 nits, resulting in impressive, at times almost blindingly bright scenes. And most importantly – this is not just a theory based on measurements. In practice, the brightest parts of films can shine with true cinematic grandeur. Fans of home HDR cinema should be truly satisfied.

The impression is excellent, especially in scenes with large areas of brightness – a white sky, explosions, sun reflections, or magical sunsets can surprise with an intensity of light that is rarely seen in this price range.

However, it gets a bit worse when more challenging scenarios appear on the screen, as described when discussing contrast – that is, images full of details, with small, bright elements on a dark background. In such cases, the C7K often decides to preserve black levels at the expense of brightness. An example? Scenes from the films Sicario 2 or Life of Pi, where small light sources (like a distant lantern) can become less visible, and details in the lights are simply dimmed or blend into the background.

For many viewers, this may be an acceptable compromise – as we achieve deep black levels and a pleasing plasticity of the image. Nevertheless, it is worth being aware that the visibility of small details in bright areas is not this model's strongest suit. It is simply a technological limitation that still exists – even with over 300 zones.

The Samsung U8000F has been tested by us in the best picture mode it offers out of the box – the Filmmaker Mode. This profile is theoretically meant to provide a neutral, cinematic image devoid of unnecessary enhancements and artificial beautifications. In the case of SDR content – primarily in HD or SD resolution – the television performed surprisingly decently right out of the box. The only noticeable flaw was brightness management. The gamma chart showed some deviations – slight brightening or dimming of certain tones – but in practice, this did not significantly affect the viewing experience. Considering the television's segment, it performs quite well.

However, the situation is much weaker in HDR mode. While the white balance was still acceptable, the colour inaccuracies were very apparent. In the Color Checker test, almost every sample was outside the target point, and the image itself appeared unnatural – the colours were shifted, sometimes too cool, other times simply dull and lifeless. The main problem lies in the hardware limitations – the U8000F does not support the wide colour gamut of DCI-P3, so it is physically incapable of reproducing the colours that the HDR standard anticipates. Unfortunately, this is evident in almost every more demanding scene.

A new feature in TCL televisions for 2025 is the long-awaited Filmmaker mode, which until now has been found in most competing brands. This is great news, as this mode is considered to be the truest to the original vision of the creators and is often recommended by enthusiasts of good picture quality. Unfortunately, as is often the case, the mere presence of this mode does not guarantee perfection. The Filmmaker mode in the TCL C7K is not without its flaws. There can be criticism of the incorrect white balance, particularly a slight dominance of blue, which resulted in cool, somewhat greyish skin tones. But that was not the biggest issue. The main complaint was the excessive brightness exposure, which is clearly visible on the gamma and EOTF graphs. The image was simply too bright, at times even blown out, which affected not only the texture of scenes but also the overall viewing experience. Some details were simply lost, and the entire image looked as if someone had slightly overcooked the brightness slider. As always, we decided to check what could be extracted from this after calibration. And that’s where it started to get really interesting…

Right out of the box, the U8000F offered quite a decent image in SDR for its price class. However, we managed to enhance it slightly – we reduced a subtle purple tint and improved the gamma characteristics, giving it a more natural curve. Despite these adjustments, the television still tends to overly brighten the brightest details – the gamma chart shows a clear inflection that cannot be completely corrected.

In HDR mode, however, it is noticeably weaker. It is hard to speak of any significant improvement here – despite attempts to adjust the settings, the image still presents considerable colour inaccuracies. A Delta E exceeding 7 signifies noticeable deviations that could not be effectively reduced. Unfortunately, this is a limitation of the construction itself – the U8000F simply was not designed for serious HDR. In everyday viewing in SDR, it performs quite well, but when it comes to HDR content... it's best not to have overly high expectations.

After calibration, the TCL C7K showcased itself in a really good light, especially when it comes to SDR content. We managed to precisely tune the white balance, colour gamut, and brightness characteristics to the point that colour errors on the ColorChecker palette dropped below a value of 2. For the uninitiated – this is nearly a perfect result, which means that the image is very close to what the creators intended. Unfortunately, the situation was worse with 4K HDR content. Although we managed to gently stabilize the white balance and correct its previous errors, it was still evident that the television has certain "MiniLED traits," especially in brightness management. When we checked how the C7K handled the EOTF curve on actual film scenes, rather than just on synthetic test patterns, it turned out that the screen still tends to slightly brighten the entire image. This impacts the overall experience – blacks lose some depth, and the image becomes less contrasty than it should be. Despite these minor shortcomings in HDR content, the overall reception of materials – especially in SDR – is truly very good. After calibration, the C7K can display an image that can compete successfully with much more expensive models. Good colour tuning, natural skin tones, and pleasant brightness make movie sessions and everyday viewing of content more than satisfactory.

When it comes to how the Samsung U8000F handles lower quality materials, we must admit that Samsung has made progress compared to its predecessor from last year – the DU7192 model, which theoretically occupies the same position in the lineup. This year's model has been equipped with a feature to improve the fluidity of tone transitions, which has been implemented much better than last year. Indeed, the television still utilizes quite strong algorithms that can distort details or remove film grain, but nonetheless – it can confidently be said that it works effectively. However, not everything has gone perfectly. The U8000F has noticeable issues with slightly cutting the image when watching very old content in very low resolution. If someone plans to play their old VHS tape, they must reckon with the fact that the image may appear slightly "cut off".

TCL C7K is equipped with a feature that, according to the manufacturer, is meant to smooth out unwanted colour transitions – a sort of rescue for less successful tonal shifts. It is called "Gradual Smoothing" and… well, it sounds ambitious, but in practice it works very poorly. Regardless of whether we set it to a low or high level, the difference is minimal. Worst of all, the feature can cut out elements from the picture that should be there. Fortunately, film grain remains untouched, so at least it doesn’t smooth everything indiscriminately, but still – it’s better to simply turn this option off.

When it comes to scaling lower resolution content, it is somewhat better. SD and HD materials look quite decent, although at times we had the impression that the image loses sharpness and becomes too soft – as if something took away its definition. Fortunately, with very low sources (e.g. 576p), there was no overscan effect, meaning the picture was not artificially cropped – everything fit on the screen as it should.

The Samsung U8000F is equipped with a 60 Hz panel, so it's clear right from the start that one shouldn't expect miracles. This is simply the standard in this class – adequate for everyday viewing, but without any fireworks. The television offers a single motion smoothing slider – a feature called "Motion Blur Reduction," which allows us to adjust the smoothness of the image in films. Higher settings produce a more "theatrical" and smoothed effect, while lower settings help retain the film's original character with a slight 24p effect. An interesting feature is "Clear Motion LED," which is the BFI mode – inserting black frames between image frames to improve motion clarity. In practice, however, the screen flickers heavily when this feature is activated and should rather be considered an experiment than something that genuinely enhances gaming comfort.

The TCL C7K handles motion fluidity really very well. The matrix used in it offers a refresh rate of 144 Hz, which in itself suggests that this television is more than just a regular "60 Hz" panel. Furthermore – if we connect the C7K to a computer and set the resolution to Full HD. But we'll write more about this in the paragraph about gamers and PC collaboration. Returning to everyday use – both sports and films look very good here. Thanks to the fast panel and well-functioning motion smoothing, the C7K is great for watching matches, but also for movie screenings. In the menu, we find two sliders – motion blur reduction and flicker reduction – which allow us to adjust the fluidity effect to our own preferences. At lower settings, we get a more cinematic effect, with slight stuttering motion. At higher settings – the picture becomes more theatrical, fluid to the point of excess. Everyone has their own preferences – anyone can set it to their liking.

[UPDATE] We have updated our 2025 Samsung TV reviews following the release of firmware version 1131, which officially restores the essential HGiG (HDR Gaming Interest Group) support.

Samsung U8000F offers a basic set of features for gamers, which may still be sufficient for less demanding users. It includes an automatic game mode – when a game is launched on the console, the television automatically switches to low latency mode, significantly improving response times. There is also a VRR feature, or variable refresh rate, which operates in the range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce the "tearing" effect – as long as we stay within this range.

Unfortunately, that’s about it for the advantages. Additions like Game Bar or higher refresh rates are reserved for higher-end Samsung models from the 2025 line. In theory, the television also supports the HGiG feature, which should adjust HDR imagery to the creators' intentions. Unfortunately – despite the fact that this feature appears in brochures and promotional materials – its configuration on the Xbox console turned out to be... impossible in practice.

The TCL C7K is a television that on paper appears to be the dream equipment for gamers – and most importantly, it holds up in practice too. To start with good news: there are two full-bandwidth HDMI 2.1 ports, so we can easily connect both a console and a computer, taking advantage of all their capabilities. The panel itself supports a refresh rate of 144 Hz, which gives a significant advantage in dynamic games. There is also a complete set of gaming features: VRR (variable refresh rate), ALLM (automatic low-latency mode), and support for Dolby Vision in games. There is also the HGiG mode, which allows for HDR effects consistent with the creators' intentions. GameBar, an information bar for gamers. It works quickly, looks clear (like a Nintendo console👌), and shows what matters most: the current frame rate, VRR status, and even HDR parameters.
